accompanied by the prescribed fee; and

(c)

accompanied, at the time the request is filed, by —

(3) The Registrar may reject any request that fails to comply with any requirement in subsection (2).

(4) The Registrar must not grant a request under subsection (1) if the Registrar is of the view that the request is frivolous, vexatious or an abuse of the process.

(5) No request under subsection (1) may be filed where there are pending before the court or the Registrar any proceedings in which the validity of the patent may be put in issue.

(6) Where proceedings before the court or the Registrar, in which the validity of the patent may be put in issue, are filed after a request under subsection (1) is made, the Registrar may make such order or give such direction as the Registrar thinks fit concerning the request.

(7) Where the Registrar grants a request under subsection (1), the Registrar must cause the specification of the patent to be re-examined by an Examiner so as to determine whether the ground specified in the request is made out.

(8) If it appears to the Examiner during the re-examination of the specification of the patent that —

(a)	the ground specified in the request; or
(b)	based on any document submitted under subsection (2)(c)(ii), any other ground mentioned in subsection (1),

is made out, the Examiner must give the proprietor of the patent a written opinion to that effect, and the Registrar must, upon receiving the written opinion, send the proprietor a copy of the written opinion.

(9) The proprietor of the patent must respond to the written opinion in the prescribed manner and within the prescribed period.

(10) Upon receiving the re-examination report prepared by the Examiner, the Registrar must send to the proprietor of the patent a copy of the report.

(11) Where the re-examination report issued under this section contains one or more unresolved objections (being an objection mentioned in the written opinion), the Registrar must make an order revoking the patent.

(12) An order under subsection (11) may be —

(a)	an order for the unconditional revocation of the patent; or
(b)	where one of the grounds mentioned in subsection (1) has been established, but only so as to invalidate the patent to a limited extent, an order that the patent should be revoked unless within a specified time the specification is amended under section 83 to the satisfaction of the Registrar.

(13) A decision of the Registrar or on appeal from the Registrar does not estop any party to any civil proceedings in which infringement of a patent is in issue from alleging invalidity of the patent on any of the grounds mentioned in subsection (1), whether or not any of the issues involved were decided in the decision.

(14) A decision of the Registrar to revoke a patent under this section has effect from the date of the grant of the patent.

(15) A person does not become a party to any proceedings under this Act before the Registrar by reason only that the person files a request under subsection (1), unless the person is the proprietor of the patent.
